Abstract

L'invention concerne un moteur (26) unique qui entraîne à la fois des pompes (24, 36) à huile et à frigorigène dans un dispositif (20) frigorifique, le moteur (26) et la pompe (24) à huile étant placés dans le réservoir (28) d'alimentation d'huile du dispositif frigorifique, et la pompe (36) à frigorigène étant placée à l'extérieur de celui-ci. La pompe (36) à frigorigène pompe du frigorigène liquide en direction de la section de compresseur du dispositif frigorifique, de façon à refroidir le moteur (22) qui entraîne le compresseur (20), alors que la pompe (24) à huile pompe de l'huile en direction de zones du dispositif (10) frigorifique qui nécessitent une lubrification lorsque celui-ci fonctionne.
